"The Air Force has confirmed its intention to extend the operations of the F-117 until 2034, meaning the aircraft will be in service for 26 years after its official retirement. Obviously, such an extension would be unorthodox, but it is not without good reasons."

so why not gives 1 or 2 F-117 to Ukraine for "research" (with big payload which do beautiful mushroom of course, you don't want to mess with the research result after all 😏 )
